T 0 (all whom it YH/II/Z/ con/newt.-

Be it known that I, CHARLES I I. COAR, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Safety Pole- Seats; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved seat for use in connection with telegraph and telephone poles, and elsewhere, where linemen and other persons are required at high elevations, and to this end the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

This device I style a safety pole seat, and it is especially adapted for application and use to poles in the vicinity of cable or junction boxes, leads attachments to poles, and are lamps located at the upper ends of the poles.

The improved seat is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views.

Referring to the drawings; Figure 1 is a plan view showing a pole with my improved safety seat applied thereto. Fig. 2 is a front elevation of the parts shown in Fig. 1, some parts being broken away. Fig. 3 is a side elevation of the parts shown in Figs. 1 and 2 and Figs. 4, 5 and 6 are detail views in side elevation showing some of the parts of the improved seat.

The body member of the seat is in the form, of a metallic yoke 1, which should be approximately horizontally disposed, with its ends rigidly secured to the pole Y by lag screws 2, or other suitable devices. The outwardly projecting portion of the yoke 1 is approximately semicircular, and the entire yoke is preferably made from a lat piece or strap of steel or iron. To support the extended portion of the yoke, inclined truss rods 3 are secured to the sides thereof, preferably by nutted bolts 1. The lower ends of the truss rods 3 are preferably secured to the pole by lag screws 5 that are formed by outward extensions 5, of the proper form to afford foot rests.

'lhe numeral 6 indicates an approximately semicircular seat strap, preferably of steel or iron, the ends of which are, as shown, preferably pivotally connected to the sides of the yoke 1 by the nutted bolts 4 already noted. This seat strap 6 works pivotally on the inner side of the yoke 1, and is adapted to be turned do\\"nward, as shown by dotted lines in Figs. 1 and 2, and by full lines in Fig. 3, to afford a suitable seat, and is adapted to be turned upward into close alinement and engage with a semicircular portion of said yoke 1 (as shown by full lines in Fig. 1). To hold the seat strap 6 in its inoperative position (shown by full lines in Fig. 1), and against accidental movement from such position, it is provided with a conical projection or nose 7, that engages with a perforation 8 in yoke 1 under the spring action of the said strap 6.

Normally, or when the seat is in use, the seat strap 6 will be turned into its inoperative position noted. In such position ample clearance is left within the yoke 1 to permit the operator to climb the pole and pass upward into the yoke. hen the operator stands with his feet on the foot pieces 5, and with his back resting against the yoke 1., or directly against the scat strap 6, the latter being then in an inoperative position, he will be held in such position as long as he sustains his weight upon his legs. \Vhen, however. the seat strap 6 is turned downward (as shown by full lines in F 3), the lineman may sit upon the same and his body will be supported thereby; at the same time the yoke 1 will hold his body against accidental displacement. hen a lineman is required to work for a considerable time in an elevated position on the pole, the seat strap 6 will be "found a very great convenience. Furthermore, a lineman or person seated on the improved seat, as above described, even in case of a severe electric shock, would not be likely to fall out of the seat.

The improved device described, while of small cost, may be easily applied to any pole, and is efficient for the purposes had in view.

What I claim is:

1. In a seat of the kind described, the combination with a metallic yoke and means for supporting the same, of a metallic seat strap pivotally connected at its ends to the sides of said yoke, and movable to and from an operative position in close engagement with said yoke, substantially as described.

2. In a seat of the kind described, cornprising a metallic yoke 1 seourable at its ends to a pole, truss rods 3 secured to the sides of said yoke and securable at its lower ends to the pole, and a metallic seat strap 6 pivotally connected at its ends to the sides of said yoke and movable to and from an operative position in close engagement with said yoke, substantially as described.

3. In a seat of the kind described, the combination with a pole, of a yoke attached thereto at its ends, truss rods attached at their upper ends to the sides of said yoke, the lower ends of which being secured to said pole, and provided with projecting foot rests, and a seat strap secured at its ends to the sides of said yoke and depending therefrom, substantially as described.

4. In a seat of the kind described, the combination with a yoke and means for securing the same to a pole, of a seat strap pivotally attached at its ends to the sides of said yoke, and means for latching said seat strap to the projecting bowed portion of said yoke, substantially as described.

In testimony whereof I afliX my signature in presence of two witnesses.

CHARLES H. COAR.
